The History of the Pregnancy Test from Rabbit Tests to Websites

A pregnancy test is used determine if a woman is pregnant or not. Today, we know that any test that detects the hormone, hCG, will offer the quickest and most accurate solution for determining if you have a baby on the way. hCG is secreted by the placenta right after a fertilized egg implants in the uterus and this hormone will show up in both your urine and in your blood. Urine pregnancy tests are great for convenient home use; but your doctor may opt to use urine or blood, as the latter can provide a “quantitative” hCG number. Both methods are quite reliable, highly accurate.
The history of the pregnancy test is an interesting one, and is naturally colored by myth, wives’ tales, and folk hypotheses. And though “ancient” pregnancy tests were typically based on false assumptions or pseudo-science, the ancient Egyptians at least knew where to start looking: they considered a woman’s urine to be the best source for prognosticating a pregnancy. To this end, the ancient Egyptians were purported to mix urine with various grains; if the grains germinated, you had a positive result, and depending on which grain germinated, you could also determine the gender: a two-in-one pregnancy and gender test! Fortunately, the Egyptians did not spend very much on patenting this technique, as it turned out to not provide very accurate results…
The Middle Ages brought us slightly more empirical techniques, though the science was still off a bit. Various physicians would closely analyze (describe) a urine sample or mix it with wine or alcohol to determine a pregnancy result. Of course, during the Middle Ages, the body was thought to be governed by the four humours (the fluids that corresponded to our “four natures”), and not influenced by hormones. So urine was studied and interpreted in the same way tea leaves might read the future – solely on the basis of how it looked. And while the descriptions of various urine results are quite detailed, it’s likely that the Renaissance pregnancy test was not very reliable either. A “smart” doctor might inquire about a few other physical symptoms in order to sharpen the accuracy of his urine prophecy.
